Paper packaging materials can be divided into five types: ordinary packaging paper, special packaging paper, trademark packaging paper, oil proof packaging paper and moisture-proof packaging paper. The paper of ordinary packaging paper is strong and flexible, and can be used for general packaging, such as kraft paper, chicken paper, etc; The special wrapping paper is named according to its purpose, and its properties are different, such as the thin and soft fruit wrapping paper; The color of the photosensitive protective paper is black and opaque; The trademark wrapping paper is used for packaging after printing, such as candy wrapping paper; Oil proof packaging paper has the property of preventing oil penetration, such as vegetable parchment and butter paper; Moisture proof packaging paper has moisture resistance, such as tar paper, aluminum foil paper, etc. According to rough statistics, there are about dozens of kinds of packaging paper.

　　The four pillars of modern packaging materials - paper, plastic, metal and glass. Among them, the growth of paper products is the fastest, the price of paper and plastic is the cheapest, the source of raw materials is wide, and it is not as fragile as glass, nor as heavy as metal, so it is easy to carry. Therefore, paper and plastic packaging are widely used in daily life. The International Health Organization and environmental protection experts believe that plastic waste may cause white pollution, which is not conducive to environmental protection. The use of plastic food bags should be gradually prohibited, and it is required to use environmentally friendly paper bags for packaging. Therefore, consumers will use non-toxic and harmless "all paper environment-friendly bags" when shopping in the future.

　　Paper packaging materials are not only rich in resources, easy to recycle, but also easy to degrade. After the paper products are decomposed, they can not only be recycled or used as plant fertilizer, but also reduce air pollution and purify the environment. Compared with other three categories of packaging materials, such as plastic, metal and glass, paper packaging is one of the most promising green packaging materials for quantitative evaluation using LCA (LifeCycle Assmcnt, or "ecological cycle assessment method") technology. At present, cartons, paper bags, paper barrels, and molded pulp products have become an important part of the modern packaging industry and are widely used in transportation packaging and food packaging.
